_Tyrannosaurus (/tɨˌrænəˈsɔrəs/ or /taɪˌrænəˈsɔrəs/ ("tyrant lizard," from the Ancient Greek tyrannos, "tyrant", and sauros (σαῦρος), "lizard" is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), commonly abbreviated to T.rex, is a fixture in popular culture. Tyrannosaurus lived throughout what is now western North America, which then was an island continent named Laramidia. Tyrannosaurus had a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the upper Cretaceous Period, 67 to 66 million years ago. It was among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event.
_Tyrannosaurus rex (tye-RAN-oh-SAWR-us-recks) is one of the most well-known of all dinosaurs. It is no longer considered the largest of the theropods. Tyrannosaurus was the last and largest of the Tyrannosaur family, or tyrant dinosaurs.
Like other tyrannosaurids, Tyrannosaurus had very short arms with only two fingers. Although these were probably nearly useless while hunting, its jaws were not: Tyrannosaurus has an enormous skull armed with teeth the size of bananas.
